Perms And Relaxers Flashcards
In what year was the first cold wave created?
1938
What do wet perms use in the processing action?
Heat
Too much tension in rolled perms causes…
Breakage and dryness
Alkaline perms have a…
Strong curl pattern
What do no Thio perms use as a reducing agent?
Cystemine hydrochloride
Wrapping end to scalp is known as…
Croquignol
Spiral hair is used on…
Medium to long hair
Active ingredient in first cold wave
Thioglycolate acid
Zonal perms are also called…
Partial perms
A neutralizer rebonds and restores the disulfide bonds in addition to which of the following?
reduces the swelling caused by the alkalinity
The perm pattern that includes a central rectangle and two sections at each side is the:
contour pattern
Hair is generally referred to as fine, medium or coarse when analyzing which of the following classifications?
texture
How do you use the bookend technique for end-paper placement?
uses one end paper folded in half.
End papers are important to control hair ends during the perming process and to:
used to control the hair ends and keep the hair smoothly wrapped around the perm tool.
At the end of the service, what should be done with open, unused perm solution?
Throw away any open, unused perm solution or neutralizer after use.
What type of perms process the fastest because of their higher pH?
alkaline perms process faster than acid waves
Which base control is the most commonly used during a perm service?
half-off base
Alkaline perms carry a pH of:
8.0-9.5.
The hair characteristics to assess in a pre-perm analysis are porosity, elasticity, texture and:
density
The rectangle wrap is also called the:
9-block pattern
Which test should be performed during a relaxer service to determine if additional smoothing is required?
The relaxation test, also known as the comb test
What is used to spread the chemical relaxer through the hair during the processing of a relaxer?
The back of the comb
Advise a client to not shampoo their hair within how many hours prior to a sodium hydroxide relaxer service?
48 hours
Virgin relaxers may be applied ¼” (.6 cm) to ½” (1.25 cm) away from the scalp because body heat from the scalp will:
allow it to spread toward the scalp
A pull test is performed to check for what condition?
elasticity
What is used to protect the scalp and hairline from chemicals?
base cream
Sodium hydroxide relaxers have an alkaline pH of:
11.5-14
Ammonium thioglycolate is a chemical reducing agent that causes the hair to:
soften
What test should be performed during a chemical relaxer procedure to determine when the hair is relaxed enough or whether additional smoothing is required?
comb test
During a curl reforming service, what size parting should be used?
thinner than normal
All of the following terms describe a type of relaxer EXCEPT:
a) sodium hydroxide
b) aniline derivative
c) potassium hydroxide
d) guanidine hydroxide
aniline derivative
The hair’s ability to absorb moisture, liquids or chemicals is known as:
porosity
The term that refers to the number of hair follicles per square inch is:
density
Why is it important to rinse the hair for a long period of time following the application of the relaxer?
to stop the chemical action
Partial perms are designed to:
position added texture within specific areas
To equalize the porosity of highly porous hair, it may be necessary to use which of these products?
pre-wrap product
The two major phases of permanent waving are:
physical and chemical
What is the main ingredient in curl boosters?
ammonium thioglycolate
What is the name of the product used to reduce the curl pattern?
curl rearranger
Sodium hydroxide relaxers are generally used on which type of hair?
tightly curled
pH of neutralizer
2.5-7.0
